Cities are seen to be thriving on exploiting the environment. If this trend, is given a free run when cities will be confronted with unsurmountable environmental problems. Ultimately the now overcrowded cities will be turned to desert lands. In this context the environmental viability of a city assumes very great significance. In order to ensure environmental viability a city “has to address itself to the various problems confronting it. A city prospers on exploiting natural resources. Natural resources are not inexhaustible. It is therefore essential that, for its survival, a city has to develop a rational approach in its exploitation of natural resources for economic growth. It should give priority to waste management, prevention of environment pollution, making provision for sanitation and health care etc. The necessity for environmental viability of a city can never be exaggerated.
